How do I deploy a cut surface on Solidworks?

3D Design Volume Model

Hi all

First post on this forum! 

My problem is the following: I am trying to generate a 3d shape by deploying a cut surface.

To put it simply, I'd like to draw my cutout from a top-down view, and then unfold the part and work from that geometry. An example in pictures.

Any idea? 

Thanks in advance!

For me it's not possible except with method to cheat! Solidworks does not know how to deploy a part. The only way would be to make a configuration with the part Draw Bend and then the part deployed, but between reality and drawing, there may be a certain margin.

Hello

If you've drawn your room and it's not closed, you can see to do like these:

I've already had this type of bag in my hands

They are designed with a rubber-based polymer

and it is true that the cuts are made via a piece on a flat piece

but to draw It under SW It's not going to be easy 

Above all, deform it from concentric cutting via the mass supports and deformation of the said bag

There is not only one deformation in one direction

The deformation is in 3 directions and both positive and negative 

so a Max job that will never be foldable under SW

Thank you for your answers. It seems complicated on SW... To tell the whole project, the bag is just an example, the idea is to generate "flattenable" 3D shapes to design springs that flatten perfectly once compressed. The curves obtained would have served as basic geometry. 

 

Beyond sw, maybe these deployment functions exist in other more specialized software? Fashion, packaging, sheet metal, ...
